I would appreciate the help. Please help me

1 Calculate F . dS, where F(x, y, z) = (z, y, 3) and S is the part of the paraboloid z = x2 + y below the plane z = 9, with upward orientation. 2 Calculate (3x cos(2x) - 3y - xy, x2 + xy?) . dr where C is the top half of x2 + y2 = 9 from (-3,0) to (3, 0), followed by the line segment from (3, 0) to (-3, 0)
